II Maccabees 12:28-38

28 But when Judas and his company had called upon Almighty God, who with his power breaketh the strength of his enemies, they won the city, and slew twenty and five thousand of them that were within,
29 From thence they departed to Scythopolis, which lieth six hundred furlongs from Jerusalem,
30 But when the Jews that dwelt there had testified that the Scythopolitans dealt lovingly with them, and entreated them kindly in the time of their adversity;
31 They gave them thanks, desiring them to be friendly still unto them: and so they came to Jerusalem, the feast of the weeks approaching.
32 And after the feast, called Pentecost, they went forth against Gorgias the governor of Idumea,
33 Who came out with three thousand men of foot and four hundred horsemen.
34 And it happened that in their fighting together a few of the Jews were slain.
35 At which time Dositheus, one of Bacenor's company, who was on horseback, and a strong man, was still upon Gorgias, and taking hold of his coat drew him by force; and when he would have taken that cursed man alive, a horseman of Thracia coming upon him smote off his shoulder, so that Gorgias fled unto Marisa.
36 Now when they that were with Gorgias had fought long, and were weary, Judas called upon the Lord, that he would shew himself to be their helper and leader of the battle.
37 And with that he began in his own language, and sung psalms with a loud voice, and rushing unawares upon Gorgias' men, he put them to flight.
38 So Judas gathered his host, and came into the city of Odollam, And when the seventh day came, they purified themselves, as the custom was, and kept the sabbath in the same place.
